Pain Associated With Interproximal Enamel Reduction in Orthodontics: a RCT

Consenting participants will be randomly allocated to one of the two groups ( motor driven device or hand driven device). A pain questionnaire in the form of a Visual Analogue Scale will be used before the treatment to determine a baseline level of pain and after the chosen treatment to determine the effect or the intervention on pain experience. After a washout period of 6 weeks the participants will crossover to have the opposite intervention carried out. A VAS will be filled in before and after the intervention again to determine a baseline pain score and pain score associated with the intervention. The data will be gathered and entered electronically into a statistical package whereby appropriate statistics will be carried out to determine if there is a significant difference in pain experienced between the two methods of enamel reduction. A secondary aim willl be to determine if there is any correlation with pain experienced and age or gender.
